SPECIFICATION forming part of Letters Patent No. 517,613, dated April 3, 1894. Application filed August 5, 1893. Serial No. 482,430- (No model.)

To all whom it may concern.-

Beit known that I, HENRY J. HENDEY, a citizen of the United States, residing at` Torrington, in the county of Litchfield and State of Connecticut, have invented certain new `and useful Improvements in a Combination Metal-Shaper; and'l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to so im p rove the construction of metal shapers as to adapt them to greater variety of work and to increase the speed with which various classes of work may be'performed. Y

My present improvements are adapted more especially to the general class of metal shapers known as traverse Shapers, the special object in view being to combine vin a single machine of this class, mechanism for producing, not onlya rapid longitudinal movement of the cutting tool but also a rapid transverse movement of the cutting tool. Heretofore in this class of machines the longitudinal movement of the tool has been rapid but `the transverse movement has necessarily been slow. In the present machine I am enabled to pro-` duce a rapid longitudinal movement of the cutting tool and an automatic feed, or by slight adjustment to so change the operation of the machine as to produce a rapid transverse movement of the cutting tool.

With these ends in view I have devised the novel combination metal shaperof which the following description in connection with the accompanyingdrawings is aspecification, numbers being used to designate the several parts. o

Figure l is a plan view partly in horizontal section, the hinged cutter head being shown vin full lines in position to make atransverse.

cut and in dotted lines in position to make a longitudinal cut; Fig. 2 a side elevation corresponding therewith; Fig. 3 a detail view,

the bed casting being in horizontal section onV the line fm, m in Fig. 2 and the clutch being disengaged as when making a longitudinal cut with an automatic feed; Fig. 4 a section of the cutter bar, saddle and bed on the line e c in Fig. l; Fig.r5 a section on the line moc in Fig. 4 Vlooking toward the left; Fig. Gasection on the line y y in Fig. 1 looking in the direction of the arrowyFig. 7 a detail sectional view on the line s s in Fig. 6; Fig. 8 a plan view of the end of the cutter bar detached, the hinged cutter head being in positionto make a longitudinal cut, this position of parts,corresponding with the position of parts illustrated in Fig. 3; Fig. 9 a similar view the hinged cutter head being detached and swung open, and Figs. 10 and 1l are respectively side and front views of the angle piece, detached, which I use to retain the hinged cutter head in position to make al transverse cut, as in Figs. l and 2.

l denotes the bed casting as a whole, 2 the table which is vertically adjustable in the usualpor in any preferred manner, 3 the saddle, and 4 the cutter bar.

Power is applied to drive the machine by means of two belts not shown either of which is adaptedto pass over a fixed pulley 5 between two loose pulleys 6 on a shaft 7 journaled in brackets S secured to the bed. One of the belts is crossed so as to reverse the movement of the machine when placed in use. Both belts are controlled by a belt shifter of ordinary construction, which when the tool is cutting either longitudinally orV transversely, may be shifted automatically or by-hand as preferred.

As any belt shifter may be used, and as the special form of shifter is not of' the essence of my invention I have not deemed it to require illustration, although I shall presently describein full the mechanism for actuating the belt shifter automatically both when a longitudinal and a transverse cut is being made. It is of course obvious that when the crossed belt is on the fixed pulley the straight belt will be on one of the loose pulleys and vice-versa, each shifting of the belts acting to reverse shaft 7. f

9 and l0 denote pinions on a sleeve 11 which is adapted to slide longitudinally on shaft 7, said sleeve being retained in place and its movement in each direction stopped by one or more pins 12 which pass through slots in the shaft, see dotted lines Fig. l, and the ends of which are fixed in the sleeve. ments ot' the sleeve are controlled by a bell The movecrank lever 13 pivoted on a bracket 14. The inner end of this lever consists of a yoke having bosses or rollers which engage a groove 15 in the sleeve. Pinion 9 is adapted to engage (and in Figs. 1 and 2 is shown as in engagement with) an idler pinion 16 journaled on a hub 17 extending outward from the bed casting. Pinion 1G in turn engages an idler pinion 1S which turns on a sleeve 19 which is itself fixed in the bed casting and through which a shaft 20 passes, see Fig. 7. Pinion 18 in turn engages a pinion 2l at the end of a screw 22 which may be used either as feed or power as I shall presently describe. This screw is journaled in suitable boxes 23 in the bed casting, one only of said boxes heilig shown, see Fig. l. The function of this screw is to move the saddle transversely on the bed by means of a depending lug 24 which extends through an opening 25 in the bed casting, see Fig. 4, and is threaded to receive the screw. I define the movement of the saddle as transverse for the reason that it is ai. right angles to the movement of the cutter bar which is commonly termed a longitudinal movement. The engagement of the saddle with the bed casting will be clearly understood from Figs. 2 and 4.

26 is a gib lying in a groove in the saddle and between the saddle and a ange on the bed casting.

Pinion 10 on sleeve l1 is adapted to engage, (but is shown in Fig. l as out of engagement with) a gear wheel 27 on a shaft 28 journaled in the bed casting in line with hub 17 but wholly independent thereof.

29 is a pinion on shaft 28 which engages a gear wheel 30 on shaft 20.

31 denotes a spline on shaft 20.

Turning new to Fig. 5, 32 denotes brackets secured to the under side of the saddle and lying in opening 25 in the bed casting. 33 denotesa sleeve which is keyed to shaft 2O so as to be carried thereby but is free to slide longitudinally thereon. This sleeve is journaled in brackets 32 and carries a pinion 34 which engages an intermediate pinion 35 on a shaft 36 which is likewise journaled in said brackets. Pinion 35 engages a rack 37 which is rigidly secured in the under side of the cutter bar, see Fig. 4 in connection with Fig. 5, thereby imparting longitudinal movement to the cutter bar. These two principal movements of the machine, t'. e. the longitudinal movement of the cutter bar and the transverse movement of the saddle will be clearly understood from Figs. l and 2 in connection with Figs. 4 and 5. The movement of the saddle over the bed casting which I term a transverse movement is produced by means of screw 22 which engages depending lug 24, and the movement of the cutter bar which I term a longitudinal movement is produced by means of pinion 34 on shaft 2Q, said pinion engaging an intermediate pinion which in turn engages a rack on the cutter bar, said pinion 34 and the intermediate pinion being carried by the saddle, and pinion 34 and the sleeve by which it is carried sliding longitudinally on the shaft 2O which imparts movement to the cutter bar.

For convenience in description I shall adopt the technical terms used in shops and describe the movement of the tool in performing work as the power and the movement of the tool transversely to its line of work as the feed.

As already stated one of the important and novel features of my present machine is that I am enabled to perform work, that is to move the tool, either longitudinally or transversely. When the tool is cutting transversely, as in Figs. 1 and 2, screw 22 is the power and shaft 20 is the feed, and when the tool is cutting longitudinally as in Fig. 8, shaft 20 is the power and screw 22 is the feed. In the first instance, that is when the tool is cutting transversely, screw 22 being the power, the feed is performed by mechanism which I shall presently describe but will first describe the mannerin which the saddle is driven in making the transverse cut. To produce this movement, 't'. e. to make screw 22 the power, sleeve 1l is moved longitudinally on shaft 7 until pinion 9 is in engagement with idler pinion 16 as already described and as clearly shown in Figs. l and 2, pinion 16 engaging idler pinion 1S which in turn engages pinion 21 on the screw. The number of teeth in the several pinions is so proportioned as to produce rapid movement of the screw and consequently rapid movement of the saddle overthe bed casting carrying the cutter bar and tool with it. It will be understood from the above, pinion 1S being an idler and shaft 28 being wholly disconnected from shaft 7, that no movement will be communicated from shaft` 7 to shaft 20, which in the present instance is the feed. I therefore provide special feeding mechanism to be used when the tool is cutting transversely and screw 22 is the power.

33, see Fig. 3, is a short shaft journaled in the bed casting.

39, see dotted lines Fig. 2, in connection with Fig. 3, is a pinion on the inner end of shaft 38 which meshes with gear wheel 30 on shaft 20.

40 is a worm wheel which is normally loose on shaft 38. The outer face of the hub of this worm wheel is provided with a clutch member 4l which is adapted to be engaged by a clutch member 42 the latter being keyed to the shaft so as to turn therewith, but free to be moved longitudinally on the outer end of the shaft so as to engage or disengage the clutch member on the hub of worm wheel 40. For convenience in illustration in Fig. 3 I have shown the clutch members as disengaged. In practice however when the machine is used as in Figs. 1 and 2, the tool cutting transversely and screw 22 being the power, the clutch members are engaged so as to lock Worm wheel 40 to shaft 38.

43 is a worm on a shaft 44 which engages worm wheel 40. This shaft is shown as placed IOO IIO

diagonally, and is provided at its outer end with a hand wheel 45, for convenience in operation. Rotationl of shaft 44 by means of the hand wheel, the clutch members being engaged, will rotate shaft 38 carrying pinion 39 which in turn carries gear wheel 30 on shaft 20,- the latter by means of pinions 34 and 35 and rack 37 imparting to the cutter bar the required amount of feed as in use or when setting the tool in position to commence work.

The capability of both longitudinal and transverse cutting movement of the tool is obtained in the manner which I will now describe. p

46 denotes the toolcarrier, 47 a tool and 48 theI usual screw for raising and lowering the tool carrier and tool. The tool carrier is secured in any ordinary or preferred manner to a cutter head 49 which is hinged as at 50 to a flange 51 at the end of the cutter bar. Flange 51 is provided with a central recess 52 and the hinged cutter head is provided with a boss 53 which is adapted to engage said recess when the cutter head is in the closed position as in Fig. 8, that is in the position in which the tool makes a longitudinal out.

In order to impart the required degree of strength andV absolute rigidity to the cutter headl and tool carrier when the cutter head is in the open position that is when the tool is making a transverse cut as in Figs. 1 and -2 I provide an angle piece 54 which is provided with a boss 55 adapted to enter recess 52. in the flange, with a recess 56 which is adapted to receive boss 53 on the cutter head, and with recesses 57 in its edges adapted'to receive bolts 58. The edges of flange 51 and the hinged cutter head are likewise provided with recesses 57 to receive bolts 58 to lock the cutter head in both of its operative positions.

When it is desired to have the tool cut transversely the bolts 58 shown in Fig. 8, are

loosened,the cutter head is swungA around as in Fig. 9, and angle piece 54 is placed between the flange and the cutter head and then rigidly secured in place by means of bolts 58 as in Fig. 1. In changing from a transverse to alongitudinal cut, bolts 58 are again loosened, the angle piece is removed and the cutter head swung back tothe position shown in Fig. 8 and locked there again by means of the bolts.' v

vSuppose the cutter head, tool carrier and tool to be in the position shown in Fig. 8, and that it is desired to produce a longitudinal cut, the operator by means of bell crank lever g 13 moves sleeve 11 longitudinally ou shaft 7,

throwing pinion 9 out of engagement with pinion 16 and throwing pinion 10 into engagey ment with gear wheel 27 on shaft 28. Movement is thus imparted by means of pinion 29 on shaft'28 to gear wheel 30 on shaft 20. Shaft 2O thus becomes the power leaving the feed to be produced by screw 22. The feed is produced automatically in 'the manner which I will now describe.

59 see Fig. 7 in connectionwith Figsrl and V2, denotes a rocker which is journaled on the outer end of shaft 20.

60 denotes a disk keyed to the shaft, 61 leather washers, and 62 a metallic disk against which a nut 63 bears in order to produce sufiicient friction of the leather washers upon the rocker pto cause the shaft to carry the rocker forward until a pin 64 on the rocker engageseither of two pins 65 which extend outward from the bed casting. When the pin on the rocker engages either of thepins 65 the rocker is held thereby until the reverse movement of shaft 2O takes place, said `movement being produced as already fully explained by the shifting of the belts on pul- 'leys 5 and 6 on shaft 7. The shaft continues to move forward after the rocker is stopped by the engagement of the pins as long as may be required to make the cut, the rocker slipping on the shaft. p

66 denotes a connecting rod which is adjustably secured to the rocker in the usual manner to permit the feed at each actuation to be increased or diminished as may be required. The opposite end of the connecting rod is pivoted to a lever 67 journaled on a hub 68 extending outward from the bed casting, see Fig. 2. At the opposite end of lever 67 is a spring pawl 69 which is adapted to engage a doublefaced ratchet 70 on the face of a pinion 71 whichis also journaled on hub 68 but wholly independently of the lever. ion 71 engages pinion 21 on screw v22 thereby imparting intermittent rotary motion to the screw and producing the feed.

The pawl is made reversible so that the machine will feed in either direction, and suitable means are provided for locking it out of operative position as for example, when placing the saddle, and with it the cutter bar and tool by hand in position to commence work, or when it is not desired to have the feed automatic. It is not deemed necessary to describe the operation of these parts more in detail as the specific construction and arrangement thereof form no portion of mypresent invention.

72 denotes adjustable dogs on the cutter headwhich are adapted to engage a lever 73 pivoted to one of the plates 74 which retain lthe cutter bar in the ways in the saddle, see

Fig. 1.

75 denotes a connectingl rod Aone end of which is pivoted to lever 73 and which slides in guides 76A upon the saddle.

A77 denotes a rack upon the connecting rod which engages a segment gear 78, see dotted lines Fig. 2, upon a rock shaft 79 journaled iu brackets 8O secured to the bed casting. Y The oscillation of this rock shaft operates a belt shifter of any ordinary or preferred construction, which is not illustrated in the drawings as it forms no portion of my present invention, to shift the belts on pulleys 5 and 6 on' `shaft 7, and thereby reverse the movement of the cutter bar, tool, dac. Dogs 72 are adjust- Pin- IOC

ed on the cutter bar by means of bolts 8l the heads of which lie in a T slot 82 in the cutter bar thereby regulating the length of the stroke. It will thus be seen that in making a longitudinal cut shaft 2O being the power and screw 22 the feed, the operation of the machine is wholly automatic, both the shifting of the belts to reverse the power, and the feed, being performed automatically in the manner just described. If it is not desired that the shifting of the belts shall be automatic in making a longitudinal cut bolts 81 are loosened and dogs 72 are moved away from each other in the T slot far enough so that they are not in contact with lever 73. This prevents automatic shifting of the belts which may then be performed by hand in the usual or in any preferred manner. SG is a suitable stop iu slot 82 which prevents the outer dog from being moved ont of the slot.

If it is not desired to have the feed automatic spring pawl 69 is locked out of operative position so that it cannot engage double faced ratchet 70 ou pinion 7l, thus throwing the automatic feeding mechanism out of operation. The feed is now produced by hand by means of a worm S3 which engages a feed nut on screw 22, see dotted lines in Fig. 2 and is held against endwise movement by a bracket 83 shown only in dotted lines in Fig. 2. The Worm is carried by a shaft S4 which extends up through the saddle and is provided with a hand lever S5 for convenience in operation, see Fig. 1. In addition to producing a hand feed if desired worm 83 may be used before the machine is started, to set the saddle, cutter bar, tool, the., in position to commence work.

Suppose now that the cutter head, tool carrier and tool are in the position shown in Figs. 1 and 2 and that it is desired toproduce a transverse cut. The operator by means of bell crank lever 13 moves sleeve 11 longitudinally on shaft '7 throwing pinion-10 out of engagement with gear wheel 27 on shaft 2S and throwing pinion 9 into engagement with pinion 16, such being the position illustrated in Fig. 1. Movement is thus imparted by means of pinions 18 and 21to screw 22 which thus becomes the power leaving the feed to be produced by means of shaft 20, pinions 34 and 35 and rack 37, see Fig. 5, and controlled by hand by means of worm 43 on shaft 44. Vhen making a transverse cut the belt shifting to reverse the power may be performed either automatically or by hand.

87, see Figs. 1 and 2 denotes collars secured to rock shaft 79 by set screws 90 and provided with outwardly extending arms 88 (one only of said collars and arms being shown).

89 denotes inclines upon the saddle which are adapted to engage arms 88 to oscillate rock shaft 79 to operate the belt shifter, in precisely the same manner thatit is operated when the machine is makingthe longitudinal cut, to shift the belts on pulleys 5 and G on shaft 7, and thereby reverse the movement of the saddle, tool, dsc. Collars 87 are adjusted on rock shaft 7 9 by means of the set screws 90, thereby regulating the length of the stroke in the same manner as when making the longitudinal cut.

If it is not desired that the shifting of the belts shall be automatic in making the transverse cut, set screws 90 are loosened and collars S7 are moved out of the way far enough so that they will not engage arms S8. This prevents automatic shifting of the belts which may then be performed by hand in the usual or in any preferred manner.
